Meta introduced Muse Spark Open, an open-weight AI model it says can match or surpass leading Chinese offerings. Aimed at coding and “agentic” tasks, the system emphasizes long-horizon reasoning and complex software engineering while touting built-in safeguards. The model is tuned for Apple’s M5 Ultra chips and can scale across two Mac Studios, signaling closer alignment with Apple but also underscoring substantial compute needs. The release, arriving days after Meta’s newest closed model, highlights a dual-track strategy as it seeks to narrow the gap with OpenAI and Anthropic and challenge China’s open-weight leaders.
